frontends (quick_frontend, primitivus): fixes room games:

- add quick_frontend.quick_games for registering the signals and registering the UI classes
    - rename the signals handlers to fit the convention (e.g.: tarotGameScoreHandler)
    - rename card_game to game_tarot, quick_card_game to quick_game_tarot, CardGame to TarotGame
